Chemistry – A European Journal, EarlyView.5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Mini‐Hairpin DNA: Extraordinarily Stable Structure and Its Applications
Chemistry – A European Journal, EarlyView.Mini‐hairpin DNA fragments containing GCGAAGC and GCGAAAGC form exceptionally stable hairpin‐like structures, with only two G−C pairs and one sheared G−A pair, remaining undenatured in 7 M urea and resisting nuclease digestion. These mini‐hairpin sequences frequently appear in replication and transcription origins, influence DNA sequencing fidelity ...

A Minimum Principle in Codon-Anticodon Interaction
, 2011 Imposing a minimum principle in the framework of the so called crystal basis model of the genetic code, we determine the structure of the minimum set of anticodons which allows the translational-transcription for animal mitochondrial code.

Clinical Pharmacology &Therapeutics, EarlyView.Thiopurine methyltransferase (TPMT) and Nudix hydrolase 15 (NUDT15) are key enzymes that catabolize thiopurines. Decreased or no‐function alleles in TPMT and NUDT15 are associated with reduced or no enzyme activity and predictive of pronounced adverse effects, including severe myelosuppression, that may occur among individuals treated with standard ...

The role of the host—Neutrophil biology
Periodontology 2000, EarlyView., 2023 Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...
